•Gently apply a slight vibration to sensors and relays in the system you are inspecting. This test may indicate a
loose or poorly mounted sensor or relay.
Engine Compartment
• There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the things
to check for are:
Connectors not fully seated.
Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
Wires laying across brackets or moving components.
Loose, dirty or corroded ground wires.
Wires routed too close to hot components.
• To inspect components under the hood, start by verifying the integrity of the ground connections (See Ground
Inspection described later). First, verify that the system is properly grounded. Then check for any loose connec-
tions by gently shaking the wiring or components as previously explained. Using the wiring diagrams, inspect
the wiring for continuity.
Behind The Instrument Panel
• An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehicle
vibration can aggravate a harness which is routed along a bracket or near a mounting screw.
• An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or
pinching.
Heat Sensitivity Test
The customer’s concern may occur during hot weather or after the vehicle has sat for a short time. In such cases you
will want to check for a heat sensitive condition.
To determine if an electrical component is heat sensitive, heat the component with a heat gun or equivalent.
CAUTION:
Do not heat components above 60°C (140°F).
If the incident occurs while heat testing the component, replace or properly insulate the component as needed.
Freezing Test
The customer may indicate the incident goes away after the vehicle warms up (winter time). The cause could be
related to water freezing somewhere in the wiring/electrical system. There are two methods to check for this:
•The first method is to arrange for the owner to leave the vehicle overnight. Make sure it will get cold enough to
duplicate the complaint. Leave the vehicle parked outside overnight. In the morning, do a quick and thorough
diagnosis of those electrical components which could be affected.
• The second method is to put the suspect component into a freezer long enough for any water to freeze. Rein-
stall the part into the vehicle and check for a reoccurrence of the incident. If it occurs, repair or replace the
component as needed.
Water Intrusion Test
The incident may occur only during high humidity or in rainy/snowy weather. In such cases the incident could be
caused by water intrusion on an electrical part. This can be simulated by soaking the car or running it through a car
wash.
Electrical Load Test
The incident may be electrical load sensitive. Perform diagnosis with all accessories (including A/C, rear window
defogger, radio, fog lamps) turned on.
Cold or Hot Starting Test
On some occasions an electrical incident may occur only when the vehicle is started cold, or it may occur when the
vehicle is restarted hot shortly after being turned off. In these cases you may have to keep the vehicle overnight to
make a proper diagnosis.

Refrigerant System Leaks
WARNING!
R-134a service equipment or vehicle A/C systems should not be pressure tested or leak tested with compressed
air. Mixture of air and R-134a can be combustible at elevated pressures. These mixtures are potentially danger-
ous and may result in fire or explosion causing property damage, personal injury or death. Avoid breathing A/C
refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved service
equipment meeting SAE requirements to discharge an R-134a system. If accidental system discharge occurs,
ventilate work area before resuming service.
NOTE :
If the A/C refrigerant system charge is empty or low, a leak in the A/C system is likely. Inspect all A/C lines, fittings
and components for an oily residue. Oil residue can be an indicator of an A/C system leak location.
NOTE :
The only way to correctly determine if the refrigerant system is fully charged with R-134a is to completely evacuate
and recharge the A/C system.
Refrigerant System Empty
1. Evacuate the refrigerant system to the lowest degree of vacuum possible. Determine if the system holds a vac- uum for 15 minutes. If vacuum is held, a leak is probably not present. If system will not maintain vacuum level,
proceed to STEP 2.
2. Prepare and dispense 0.3 kilograms of R-134a refrigerant into the evacuated refrigerant system and proceed to STEP 1 of the System Low procedure.
Refrigerant System Low
1. Position the vehicle in a wind-free work area. This will aid in detecting small leaks.
2. Operate the heating-A/C system with the engine at idle under the following conditions for at least 5 minutes:Doors or windows open, transaxle in Park or Neutral with the parking brake set (depending on application), A/C-
Heater controls set to outside air, full cool, panel mode, high blower and with A/C compressor engaged.
3. Shut the vehicle Off and wait2-7minutes. Then use an electronic leak detector that is designed to detect R-134a refrigerant and search for leaks. Fittings, lines or components that appear to be oily usually indicate a
refrigerant leak. To inspect the A/C evaporator for leaks, insert the leak detector probe into the drain tube open-
ing or an air outlet. A dye for R-134a is available to aid in leak detection. Use only approved refrigerant dye.
CAUTION:
A leak detector only designed for R-12 refrigerant will not detect leaks in an R-134a refrigerant sys-
tem.

3. Open both the suction and discharge valves, then open the charge valve to allow the refrigerant to flow into the system.
4. When the transfer of refrigerant has stopped, close both the suction and discharge valves.
5. If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle and set the heating-A/C system controls so that the A/C compressor is operating and the blower motor is running
at its lowest speed setting. Run the engine at a steady high idle (about 2000 RPM).
6. Open the low-pressure valve to allow the remaining refrigerant to transfer to the refrigerant system.
WARNING!
Take care not to open the discharge (high pressure) valve at this time. Failure to follow this warning could result
in possible personal injury or death.
7. Disconnect the refrigerant recovery/recycling station from the refrigerant system service ports.
8. Reinstall the caps onto the refrigerant system service ports.
Compressor
Description
Vehicles equipped with the 1.6L & 1.8L & 2.0L engine use a SD7V16 clutch-less compressor. The 2.4L equipped
vehicles use a V5 clutch-less compressor. The compressor is a variable displacement compressor. The largest dis-
placement is 161.3 ml/r, displacement range of 5% to 100%.
CAUTION:
DONT run the engine with a vacuum pump in operation or with a vacuum present within the A/C
system. Failure to follow this caution will result in serious A/C compressor damage.
NOTE :
The compressor drive hub and the pulley and bearing assembly cannot be serviced separately from the A/C com-
pressor. In the event of drive hub or pulley and bearing assembly damage or failure, the A/C compressor, drive hub
and pulley and bearing must be replaced as an assembly.
Operation
The A/C compressor is controlled by the Engine Control Module (ECM), depending on engine application. The ECM
calculates compressor displacement required by A/C system load and demand by monitoring vehicle speed, A/C high
side pressure, engine speed, evaporator temperature, accelerator pedal position, ambient temperature and A/C-
Heater request signals. The ECM then sends a pulse width modulated signal to the A/C compressor control solenoid
to increase or decrease refrigerant flow through an orifice located within the compressor housing. The amount of
refrigerant allowed to pass through the orifice in the compressor determines the head pressure which controls the
angle of the swash plate, which in turn, determines the amount of compressor displacement. When there is no
demand for A/C, the swashplate is adjusted to nearly a zero degree angle, which removes compressor torque drag
from the engine.
NOTE :
The A/C compressor cannot be repaired and it must be replaced if found inoperative or damaged. If an internal fail-
ure of the A/C compressor has occurred, the A/C accumulator and the A/C liquid line must also be replaced.
Removal & Installation - 1.6L & 1.8L & 2.0L
